STOVEPlPE-BOILER. a

SLPEGIFIGATION forming part of Letters Patent No. 717,943, dated J anuary 6, 1903.

Application filed January 16, 1902- Serial No. 90,013. (No model.)

T on whom, it may concern.-

Be it known that I, MELVIN G. STRICKLAND, a citizen of the United States, residing at Lynchburg, in the county of Campbell, State of Virginia, .have invented certain new and useful Improvements in Stovepipe-Boilers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to water heaters or boilers; and it has for its object to provide a device of this nature which may be directly engaged with the pipe-receiving collar surrounding the smoke-hole in the top of a stove, the boiler being of such construction that the heat from the smoke-hole will be directed against the bottom of the boiler and will follow closely against the inner surface thereof.

A further object of the invention is to provide a construction wherein clinging of soot to the lower end of the boiler will be prevented.

Other objects and advantages of the invention will be understood from the following description.

In the drawing forming a portion of this specification there is shown a vertical section through a boiler embodying the present invention and showing a portion of the top of a stove to which it is attached.

Referring now to the drawing,there is shown a boiler, including a central major cylindrical portion 5, forming the outer member of the water-holding portion of the device and the lower end of which-is reduced in diameter, as shown at 6, for direct engagement over the collar 7 at the smoke-opening of the stove, the upper end of the member being likewise reduced in diameter for engagement of a section of smoke-pipe therewith.

The inner member or lining 9 of the boiler is of tubular form, and the ends thereof are flared, as shown at 10 and 11, and are riveted against the shoulders 12 and 13, respectively, which are formed by the reduction of the ends of the member 5, as illustrated. The lining 9 is of lesser diameter than the reduced ends of the outer member, so that the lining has the shoulders 15 and 16 at its upper and lower ends, respectively, and the flames emerging from the smoke-hole of the stove impinge directly against the lower shoulder, so that the greatest efficiency is secured. At the upper end of the lining or member 9 is a damper consisting of a disk 17, mounted upon a shaft 18, passed through the sides of the reduced upper end of the member 5, said shaft having a handle 19 at one end for oscillating it to open and close the duct through the boiler to the proper degree. 'At the upper portion of the member 5 is an inlet-opening 20, having a suitable closure, while at the lower portion thereof is a faucet 21, through which the-water from the boiler may be d rawn.

In practice other modifications of the invention may be made, and any suitable ma terials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is A device of the class described comprising an outer cylindrical member having its ends reduced to form shoulders and an inner cylindrical member of lesser diameter than the reduced portions of the outer member, the

ends of said inner member being flared and secured against the inner faces of the shoulders of the outer member.

In testimony whereof I affix my signature in presence of two witnesses. 1
